By 2050，a completely new type of human evolve as a result of extremely new technology，behavior，and natural selection．This is according to Cadell Last，a researcher at the Global Brain Institute，who claims mankind is undergoing a major"evolutionary transition"．

In less than four decades，Mr．Last claims we will live longer，have children in old age and rely on artificial intelligence to do ordinary and boring tasks．This shift is so significant，he claims，it is comparable to the change from monkeys to apes，and apes to humans．"Your 80or 100is going to be so radically different than your grandparents，"Mr．Last says，who believes we will spend much of our time living in virtual reality．Some evolutionary scientists believe this age could be as high as 120by 2050．

Mr．Last claims humans will also demonstrate delayed sexual maturation，according to a report by Christina Sterbenz in Business Insider．This refers to something known as life history theory which attempts to explain how natural selection shapes key events in a creature's life，such as reproduction．It suggests that as brain sizes increase，organisms need more energy and time to reach their full potential，and so reproduce less．

Instead of living fast and dying younger，Mr．Last believes humans will live slow and die old．"Global society at the moment is a complete mess，"he told MailOnline．"But in crisis there is opportunity，and in apocalypse （启示） there can be transformation．So I think the next system humanity creates will be far more sophisticated，fair，and abundant than our current civilization．"

"I think our next system will be as different from the modern world，as our contemporary world is from the medieval （中世纪的） world．The biological clock isn't going to be around forever，"he added，and said that people could pause it for some time using future technology．

The change is already happening．Today，the average age at which a woman in
